Abstract
Schmidt hammer test as an indirect method has so far been widely applied for determining the physical properties of intact rock, and many researchers have developed procedures for its use on rock cores, blocks and in field. Though many methods have developed upto date for indirect using, the almost were single blow which has many errors. The purpose of this study was to evaluate the established as for ASTM, ISRM, BSI, Poole & Farmer and Hucka method and to suggest a new optimum test method and statistical analysis on rocks. The finding has indicated that succeeding blow has served as an optimal to predict physical properties of rocks. To conduct the experiment, researchers have examined 150 rock blocks, which include igneous, metamorphic and sedimentary rocks in Korea nation wide.
